WILLIAM HERBERT HALL, OF OSHAWA, ONTARIO, CANADA, ASSIGNOR TO THE PEDLAR PEOPLE LIMITED, OF OSHAWA, ONTARIO, CANADA.

METALLIC SHINGLE.

Specification of Letters Patent.

To all whom it may concern:

Be it known that I, WILLIAM HERBERT HALL, a subject of the King of Great Britain, and resident of Oshawa, in the Province of Ontarlo, Dominion of Canada, have mproved construction hereinafter described in detail in the accompanying specification and drawings.

In the drawings,

Figure 1 is a perspective view of the shingle embodying the present invention.

Fig. 2 is a longitudinal section through two shingles connected.

Fig. 3 is a transverse section through two shingles connected.

Fig. 4 is a plan view of the blank from which the shingle is formed.

Fig. 5 is a perspective detail of the lower corner of the shingle.

Fig. 6 is a perspective view of the upper corner of the shingle.

Fig. 7 is an enlarged sectional detail through the side joint. I

In .the drawings like characters of reference indicate corresponding parts in all the Referring to the drawings, A represents the body portion of the shingle which may in holding the shingle in place and form a water barrier.

The side lock on the adjacent shingle is formed bya trough shaped flange 14 on one side of the body portion of the shingle adapted to receive a corresponding tongue shaped flange 15 on the opposite side of the shingle.

In accordance with the present invention the bottom of the trough shaped flange 14 is substantially on a level with the bottom of the body portion and the trough shaped flange is formed with a longitudinally extending ridge 16 which extends upwardly Well above the top surface of the body portion and is adapted to fit into a corresponding longitudinally extending recess 17 formed in the tongue shaped flange 15.

This interlocking ridge and recess is an important feature of the invention as it prevents any leakage of water on the side joint and forms a water barrier between ad: jacent shingles. .lt projects substantially above the surface of the body portion, that is to say above the planes of the tops of the flutings 10, and it will also be observed that the bottom of the trough shaped flange does not project below \the plane of the lower edges of the flutings. In this way a more substantial bearing on the roof is maintained.

Previously in many forms of shingles the trough shaped flange projected below the surface of the shingle which caused the body portion of the shingle to be supported above the roof rendering it liable to be bent easily by pressure from the outside.

The top and bottom lock are formed by an underturned flange 20 on the bottom of the shingle adapted to engage an overturned flange 21 on the top of the shingle, both of said flanges being hook shaped in form.

To provide a continuous bottom joint, a portion of the trough shaped flange 14 and the tongue shaped flange 15 are turned up to correspond with the flange 20 to thereby enable this underturned flange to extend in a continuous manner across the body portion of the shingle and across both the trough shaped flange and the tongue shaped flange as clearly shown in Fig. 5 of the drawings.

On the upper end of the shingle the overturned flange 21 is bent at the side 23 into engagement with the trough shaped flange and the top portion 25 of the trough shaped flange is extended and bent upwardly slightly to form a water stop as shown in Fig. 6 of the drawings.

What I claim as my invention is:

1. A metallic shingle having a trough shaped flange formed on one side with a ridge projecting upwardly above the surface Patented Mar. 6, 1917.

of the shingle and having a tongue shaped flange on the opposite side adapted to enter the trough shaped flange of a corresponding shingle, said tongue shaped flange having a recess therein to receive the ridge in the trough shaped flange and a ater stop formed at the top of the trough shaped flange formed'by turning upwardly a pro- .jecting portion of the flange? 2. A metallic shingle having side joints below the plane of the surface of theshingle, being also formed With interlocking top and bottom joints, the surface of the shingle being formed With a plurality of par-
